Abstract

The present invention relates to an electrical arc interruption chamber, in particular for fluid-quenched circuit breakers, in which, inside a tightly sealed insulating encasing, containing an arc-quenching gas, provided are current-bearing connections, respectively supporting a movable main contact and a stationary main contact, each one of the main contacts being provided with its respective arc contact, and wherein the movable arc contact of the tulip type is positioned inside a wall element of insulating material, having, e.g., the shape of an upside-down bell, the movable contact and the bell-­shaped element being housed inside the body of the movable main contact, in order to define a first chamber for the passage of the arc-quenching gas between the said body and the said insulating element, defined being furthermore a second chamber for the passage of the arc-­quenching gas, which is movable between the movable arc contact and the bell-shaped element.
